The tiny chips, implanted in the flesh between the thumb and forefinger, are similar to those for pets. They enable people to open their front door,
access their office or start their car with a wave of their hand, and can also store medical data.

Another company, Biohax of Sweden, also provides human chip implants the size of a grain of rice. It told the Sunday Telegraph (£) that it is in
discussions with several British legal and financial firms about fitting their employees with microchips, including one major company with hundreds of
thousands of employees.
